Sarge to Etch upgrade - PHP5 failed

Very long story short I tried to upgrade from Sarge to Etch and everything seems to look okay, other than PHP5 failed.

<code>
atest:~# /etc/init.d/apache2 force-reload
Forcing reload of web server: Apache2 ... failed!
You may still have some apache2 processes running. There are
processes named 'apache2' which do not match your pid file,
and in the name of safety, we've left them alone. Please review
the situation by hand.
Syntax error on line 1 of /etc/apache2/mods-enabled/php5.load:
API module structure `php5_module' in file /usr/lib/apache2/modules/libphp5.so is garbled - perhaps this is not an Apache module DSO?
atest:~#
</code>

I've googled around and keep coming up with people walking through compiling Apache2 from source which is NOT what I want to do

If it has any relevance, this is the same box you'd made some recommendations on to install rsycn because it wanted to replace the kernel, with the same one. (that is what lead to to fully upgrading the box)
